CPU Usage per program

I have been asked to build something like the task manager, I need to get a list of processes and how much of the cpu they are using in % value.

These dont need to be running counts i just need what percentage of the cpu was being used when my application started up.

I am getting the cpu percentage using the below code

Public Shared Function GetCpuUsage() As Integer

    Dim myCount As Integer
    Using cpu = New PerformanceCounter()

        With cpu
            .CategoryName = "Processor"
            .CounterName = "% Processor Time"
            .InstanceName = "_Total"
        End With

        myCount = cpu.NextValue()
        System.Threading.Thread.Sleep(1000)
        myCount = cpu.NextValue()
        System.Threading.Thread.Sleep(1000)
        myCount = cpu.NextValue()
    End Using

    Return myCount
End Function

The question I have is how would i get the % value of each process that is using any cpu usage and ignore anything that is at 0?
